Intel Core i7-7700k Contrast i7-6700k which is better? Intel Kabylake and 200 series simply say As mentioned above, the 200 series chip group from B250, H270 to Z270, its wafer PCIe channel number increased, providing more bandwidth increase use, so you can see at least one PCIe X4 storage device, and the other memory frequency from 2400MHz, performance will be improved, Another high-profile Intel Optane memory needs to use the H270 and Z270 motherb

NVM, the access characteristics of Byte addressable, and the way RDMA is accessed, the distributed NVM + RDMA needs a new architecture design, including single-machine data structure, distributed data structure, distributed consistency algorithm and so on. In this regard, the Tsinghua computer department published last year's Octopus provides a way of thinking, through the NVM + RDMA implementation of the Distributed file system, while the implementation of a set of RDMA-based RPC for inter-nod
